Hello,
I would like to know if the changes described in the PCN 20241015003 are the reason why the electrical parameters of the PCN #20241015002.1 are changing, or if these changes were made to correct previous erro…

Hi,
If you use a device with Dmax = 100%, while you design external try to work < 50%, it depends on how your external circuit is designed. If there is no 50% duty cycle clamp, during transient > 50% duty cycle can still be there which can cause unstable…

Hello Team
I am writing to inquire about the recent specification change noted in PCN#20241015002.1, where the minimum value of the PWM maximum duty cycle for the UC2843AN has been adjusted from 94% to 92%.
We understand…

Hi team,
I designed isolated flyback converter with opt coupler feedback. VIn=500V, Vout=8V, Po=16W at Fsw=100kHz.
When I reduce the load current to near 0A, then the switching frequency drops to 10kHz.
Is this…

Hi team,
UCC2843A-Q1 doesn't have Vc pin as datasheet page 8.
Is this Vc connected to Vcc internally?
In that case, OUTPUT High Voltage can be as high as Vcc?
I plans connect Vcc>15V, so I wonder if it is clamped…

Hi,
This is an urgent request. My customer is requesting simulation model for UC2843A-Q1. Do we have simulation model in SIMPLIS or PSpice? I did…
Hello Respected ,
Please help to reconfirm operation voltage range for part UC2843AD8 .

Hi,
I have designed a synschronous buck converter with uc2843A . I have derived slope compensation ramp from pwm output through RCD circuit to generate a adjustable ramp duty cycle. ramp is add to CS pin. The issue which I am facing…
